Full autonomous vehicles, and particularly significant levels of adoption of them are decades away. It's taken roughly 20 years for hybrid vehicles to become "big", and that's after the tech already existed. We still don't even have anywhere close to reliable full autonomous driving.
It usually is much more effective to make plans and changes based off what currently exists rather than anything that isn't absolute immediate future. No reason to say no to the good because you're busy waiting for "perfect".
